Letters Patent No. 100,860, dated March 15, 1870.-

IMPRQVEMENT IN RAILWAY-CAR Axnes.

. The Schedule referred to in these Letters 1-"a'ten1:` and making part oi' the s ame.

To all whom Muay concern:

Be it known that I, CHALns COLE, of Troy, county of `Rensselaer, and State of New York, have invented certain uewand useful Improvements in'l Compound vCompensating Car-Axle and -to enable others skilled lin the art fto make -and use the same, I will proceed to describe its construction, referring to the drawings,- in which the same letters indicate like parts in each ot' the figures.

The nature of this vinvention consists informing each axle iu 4two parta-and uniting the two inner ends by means of rocking or oscillating boxes irmly arranged inside of a eoupling-case, and this case firmly secured to the underside ofthe car, between the wheels or. the common axle journal-boxes.

rIl he obje-ctofthis invention is `to secure compensa- I tionl for the extra surface one Wheel has to travel more than the other whileV running over curves.

It is often the' case that a train of cars running at its usual'speed, having the axles andwheels' as now constructed, is brought almost to a dead stop, whereas, if jeach wheel was free to turn, or to adapt itself independently one ofthe other to the surface it `has to run over, thisl diiiiculty would be avoided, and

which', by `the use of this invention, will nearly or.

quite remove the ditliculty experienced as now cou- 'inside of the wheels, the inner ends of this axle are providedv with bearings 71"?) and collars c c, andare tted into the bearings of the oscillating boxes d d; 'One or both of these boxes d d are provided with an oil or lubricating reservoir, e. These boxes, when closed together over the bearings of the axle, are round, and

are tted into chambers or bearingsf, formed in the coupling-case g. These coupling-casesare .provided with flanged collars It h, so that when the tivo parts g g are. firmly secured together, in any of the-common ways of securing journal-boxes together, they are placed within the clasp case t', and the whole firmly secured to the under timber of the car.

k are .lubricating orices. It will be clearly seen that when the axle is thus made in two tparts and properly tted into oscillating boxes d, and these boxes also properly tted and secured together, and placed within the couplingcase g and the coupling-case or its equivalent, is secured to the under side ofthe car, while all of the other parts, y the wheels, journal-boxes, Ste., are coustructedin the common way, there will be less strain upon the axle, less resistance or friction to retard the motion, or. to take up the power of the engine.

l have udeavored to show the nature, construction, and advantage of thisinvention, so as to enable others skilled in the art to make and ulse the same therefrom. l

- What I claim, and desire to secure by Letters Patent, is l The voscillating boxes d, arranged in the coupling- -case g, in combination with the shaft a and clasp case z', substantially as set forth.

- CHARLES COLE.
